WTP TYPES

Ensuring Pure and Safe Water through Innovative Filtration Technologies

Sand Filters

Efficient Removal of Suspended Particles and Turbidity

Sand filtration is a physical process that involves passing water through a bed of granular material, typically various grades of sand and gravel to remove suspended solids and reduce turbidity. As water flows through the sand layers, particles are trapped within the pores, resulting in clearer water. Sand filtration done through a pressure i.e pump are known as pressure sand filters. Based on the sand media they are differentiated as Pressure Sand Filter, Mult-Grade Sand Filter and Dual-Media Filter.

Materials of Construction (MOC) :

  • Filter Vessel : Constructed from materials like Mild Steel (MS), Stainless Steel (SS), or Fiber Reinforced Plastic (FRP), selected based on application requirements and corrosion resistance.
  • Filter Media : High-grade silica sand is commonly used for its uniform size and effective filtration properties.

Activated Carbon Filters

Advanced Adsorption for Chemical and Odor Removal

Activated Carbon Filters utilize the adsorption process to remove dissolved organic compounds, chlorine, and other chemicals that affect water taste and odor. The activated carbon's porous structure provides a large surface area, allowing it to effectively trap contaminants as water passes through. This filtration is crucial for eliminating undesirable tastes, odors, and harmful chemicals, ensuring high-quality potable water.

Materials of Construction (MOC) :
● Filter Vessel : Available in MS, SS, or FRP, chosen based on specific application needs and durability considerations.

● Filter Media : Granular Activated Carbon (GAC), derived from sources like coconut shells or coal, known for its high adsorption capacity.

Nirtech Industrial Water Softeners

Nirtech's industrial water softeners utilize the ion-exchange process to effectively remove hardness ions from water. This process involves passing hard water through a resin bed where calcium (Ca²⁺) and magnesium (Mg²⁺) ions are exchanged for sodium (Na⁺) ions, resulting in softened water. The resin, once saturated with hardness ions, undergoes regeneration using a brine solution, restoring its softening capacity. The regeneration cycle typically includes steps such as backwashing, brine injection, slow rinse and fast rinse to ensure optimal resin performance.

Materials of Construction (MOC) :
Nirtech's industrial softeners are constructed using high-quality materials to ensure durability and reliability :

● Resin Vessel : Fabricated from carbon steel / mild steel interior epoxy coating to prevent corrosion and ensure structural integrity. FRP vessel also available for flow less than 10m3/hr.

● Face Piping : Available in uPVC or galvanized steel, chosen based on the specific application requirements to withstand varying pressures and temperatures.

● Internal Distributors : Constructed from uPVC to provide efficient water distribution and collection within the system.

Nirtech's Ultrafiltration Systems : Superior Water Purification Solutions

At Nirtech, we specialize in providing advanced ultrafiltration (UF) systems that deliver exceptional water purification for various applications. Ultrafiltration is a pressure-driven process that separates particulate matter from soluble compounds using ultrafine membrane media. The feed water passes through hollow fiber membranes, where contaminants are retained, and purified water permeates through. This method is highly effective for desalination pretreatment, reverse osmosis pretreatment, wastewater reclamation, and producing potable water.

Materials of Construction (MOC):

The performance and durability of UF systems largely depend on the materials used in their construction. Nirtech utilizes high-quality materials to ensure optimal functionality:

  • Membrane Materials :  UF membranes are crafted from robust polymer materials such as Polyether Sulphone (PES) or PolyVinyl DiFLuoride (PVDF). These materials offer excellent chemical resistance and mechanical strength, making them ideal for various water treatment applications.

  • Module Housing : The housing units for our UF membranes are constructed from PVC that can withstand varying operational conditions, ensuring longevity and consistent performance.

  • Support Structures : We incorporate high-strength materials in the support structures of our UF systems to maintain structural integrity and facilitate easy maintenance.

Efficient and Reliable Spiral Reverse Osmosis Solutions for Diverse Applications

At Nirtech, we specialize in designing and manufacturing advanced spiral reverse osmosis (RO) plants tailored to meet the unique water and waste water purification needs of various industries. Our commitment to quality and innovation ensures that our RO systems deliver exceptional performance, durability, and efficiency.

Reverse osmosis is a water treatment process that removes dissolved salts, virus, contaminants by forcing water through a semi-permeable membrane under pressure. This method effectively eliminates dissolved salts, organics, bacteria, and pyrogens, producing high-purity water suitable for industrial, commercial, and residential applications.

Key Components and Materials of Construction (MOC) in Nirtech’s RO Plants :

Feed Pump : The feed pump pressurizes the incoming water, driving it through the RO membrane. Proper pressurization is crucial for efficient contaminant removal.Typically constructed from stainless steel to resist corrosion and ensure longevity, especially when handling varying water qualities.

High-Pressure Pump : This pump increases the pressure of pre-treated water to levels necessary for the reverse osmosis process, enabling the separation of impurities through the membrane. Constructed from duplex stainless steel or other high-grade alloys to handle high pressures and provide excellent corrosion resistance.

RO Membrane Housing (Pressure Vessels) : Houses the RO membranes where the separation of pure water and concentrated dissolved salts, bacteria greater tah nsize of 0.001micron occurs. Made from materials like fiberglass-reinforced plastic (FRP) or stainless steel, chosen based on operating pressure requirements and chemical compatibility.

RO Membranes : Typically thin-film composite (TFC) membranes composed of a polyamide active layer supported by a polysulfone layer, offering high rejection rates and durability. Brackish water, Seawater Membranes are used based on the TDS.

Control and Monitoring Systems : Automated systems that monitor and control the RO plant’s operations, ensuring optimal performance, safety, and efficiency. Enclosures and components are made from industrial-grade materials designed to protect sensitive electronics from environmental factors and ensure reliable operation.

Water Treatment Plant (WTP) – FAQ

Sand filters effectively remove suspended solids, turbidity, and particulate matter from water.

The frequency of backwashing depends on the water quality and usage but is typically performed when the pressure drop across the inlet and outlet is more than 0.8 bar.

? Yes, sand filters are versatile and can be scaled for both residential and industrial water treatment needs.

Regular backwashing and periodic inspection of the sand media are essential to maintain the filter's efficiency.

An activated carbon filter uses porous carbon media to adsorb impurities, removing contaminants from water.
